RPMs - please read the message from Administrator McCarthy at the end of this string of
emails. As you will see in the highlighted passage, we are being instructed to cease investigatory
work at mining sites. I am not aware of any such work going on at any of our 5 mining sites right
now. Please confirm this is correct (reply to all ). Also, please let me know if any mobilizations
are planned in the next few months for investigatory work (reply to all). Please reply by 4: 15
today. Thanks,

Don

Good morning everyone,

While we continue to investigate the root causes of last week’s release of mining waste at
the Gold King Mine in Colorado, we are instructing our Regions to immediately cease any
field investigation work at mines including tailings facilities, unless there is imminent risk
in a specific case. We are in the process of initiating an independent assessment by a sister
federal agency or another external entity to examine the factors that led to last week’s
incident. Based on the outcome from that assessment, we will determine what actions may
be necessary to avoid similar incidents at other sites. While we stand down on existing field
investigations and assessments at these mining sites, we also are instructing our Regions to
identify existing sites with similarities to the Gold King Mine site and to identify any

immediate threats and consider appropriate response actions.

If you have questions or wish to discuss a particular situation please reach out to Mathy.

Thank you.
